RE: [EnergyPlus_Support] Controller Error

Jean, Alberto and Jim,

thanks for helping me, but the error persist.

I'm sending the idf model. Perhaps you able to view the error easily. I'm actually don't know why this is happening. It's the first time i'm seeing this.

Thanks a lot for this!

Respectfully disagreeing ?.  HVAC Cooling coils are always reverse action.  This is specified in the Controller:WaterCoil object (example below).  I do not recall all of the several ways that I have erred in order to receive this message, but I think improper setpoints are the most common.  Your 12.8C setpoint looks OK, but perhaps there is a zone setpoint that is improper?

Dear Ivan,


You should change the status of reverse action of the colling coil controller .
